here is the case study to be analyzed: "Susan and Lucy are both international students from Narnia and in the same science class. Lucy has a strong grasp of the English language and is doing well in her classes. Susan's grasp of the English language is not nearly as strong as Lucy's. With Lucy's help, she's working hard to expand her standard English vocabulary, plus learn all of the science vocabulary. But Susan is having a hard time retaining the information, most likely because she isn't eating or sleeping well. One day, there is an exam in their science lab. Susan is having a hard time understanding what is being asked in the questions and therefore doesn't know what to put down for the answers. She starts to panic that she'll fail the lab and the class. The TA notices that Susan and Lucy are talking to each other in Narnian and he asks them what they are talking about. Lucy explains that she is only translating the questions for Susan. The TA asks them not to talk and if Susan has questions about the test, then she should bring them to him (the TA). Susan asks him about one of the questions, but the TA can't explain it without giving away the answer, so Susan goes back to her seat, uncertain what to do. Twice more during the exam, he catches Susan and Lucy talking in Narnian. Again, he tells them to stop talking. The TA knows Lucy is a solid student and thinks it is very possible that Lucy is only translating the question and is not providing Susan with the answers, but he isn't sure. He decides to report the situation to the professor who teaches this section"
